My research seeks to develop a predictive understanding of species invasions, using a combination of field experiments, empirical modelling and meta-analysis. My students and I examine why some species are better invaders than others, why some cause greater impacts, and why some ecosystems are more vulnerable to invasion. Most of our work is focused on the ecological impacts of invasive species in lakes and rivers.

Current research work:

Testing new theories regarding the success and impact of introduced species

Examining the ecosystem-level effects of invaders in the St. Lawrence River
